qiuyanjun888 opened a new pull request, #4479: URL: https://github.com/apache/flink-cdc/pull/4479
## What is the purpose of this pull request? Fix [FLINK-40152](https://issues.apache.org/jira/browse/FLINK-40152), where the PostgreSQL CDC connector captures case-variant tables even when only one table is configured. PostgreSQL quoted identifiers are case-sensitive, but the Debezium table include predicate is case-insensitive by default. ## Brief change log - Preserve the existing Debezium table filter and additionally apply the effective `table.include.list` as case-sensitive full-match regular expressions. - Reapply the case-sensitive filter after split-specific PostgreSQL connector configurations are rebuilt. - Add unit coverage for regex matching, case-only sibling exclusion, and connector-config reconstruction. --- ## Verifying this change This change added tests and can be verified as follows: - Added `PostgresSourceConfigTest`. - Ran `mvn -pl flink-cdc-connect/flink-cdc-source-connectors/flink-connector-postgres-cdc -am -Dtest=PostgresSourceConfigTest -Dsurefire.failIfNoSpecifiedTests=false test`. - Result: 2 tests passed; Spotless, Checkstyle, production compilation, and test compilation passed. ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Hermes Agent with OpenAI Codex (GPT-5.6) Generated-by: Hermes Agent with OpenAI Codex (GPT-5.6) -- This is an automated message from the Apache Git Service.
